In the BRAS transfer control separation architecture shown in fig. 1, the UCM device may allocate a BRAS CP device to a BRAS DP device that starts a BRAS service, and control the BRAS CP device to establish a connection for performing message interaction with the BRAS DP device, and then the interaction between the BRAS CP device and the BRAS DP device (including user online control message processing, user flow control message, and the like) is directly performed without being shunted by a centralized load balancing device, so that a performance bottleneck and a single point failure risk are avoided, the resource pooling scale is improved, and the user online rate can be significantly improved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a schematic flow diagram of a message forwarding method according to an embodiment of the present invention is provided, where the message forwarding method may be applied to a UCM device in a BRAS handover control separation architecture shown in fig. 1, and as shown in fig. 2, the message forwarding method may include the following steps:
In the embodiment of the present invention, the target BRAS DP device does not refer to a fixed BRAS DP device, but may refer to any BRAS DP device in the BRAS diversion separation architecture shown in fig. 1.
In the embodiment of the invention, when the target BRAS DP equipment starts the BRAS service, the UCM equipment can select one BRAS CP equipment for processing the control message of the target BRAS DP equipment from the BRAS CP resource pool.
For example, the UCM device may assign a target BRAS CP device from a BRAS CP resource pool to the target BRAS DP device upon detecting a BRAS service initiation command for the target BRAS DP device.
In one embodiment of the present invention, the allocating a target BRAS CP device from BRAS CP devices to a target BRAS DP device in BRAS DP devices, may include:
and respectively allocating corresponding target BRAS CP equipment to each interface for starting the BRAS service on the target BRAS DP equipment from the BRAS CP equipment.
In this embodiment, when the UCM device allocates the target BRAS CP device to the target BRAS DP device, the target BRAS CP device may be allocated with an interface of the BRAS DP device as a granularity, that is, the target BRAS CP device corresponding to each interface on the target BRAS DP device that starts BRAS service is allocated.
Accordingly, when the UCM device receives a command to start BRAS service for any interface of the target BRAS DP device, the UCM device may select a target BRAS CP device from the BRAS CP resource pool for processing a control packet received by the target BRAS DP device through the interface.
Optionally, the receiving of the BRAS service initiation instruction for the interface of the target BRAS DP device may include:
acquiring interface information of target BRAS DP equipment, and displaying the interface information of the target BRAS DP equipment;
when an operation instruction of starting the BRAS service at a certain interface of the target BRAS DP equipment is detected, the BRAS service starting instruction aiming at the interface of the target BRAS DP equipment is determined to be received.
In this embodiment, after the UCM device establishes the Netconf connection with the target BRAS DP device, the UCM device may obtain the interface information of the target BRAS DP device.
For example, after the target BRAS DP device establishes the Netconf connection with the UCM device, the target BRAS DP device may report its own interface information to the UCM device.
After the UCM equipment acquires the interface information of the target BRAS DP equipment, the interface information of the target BRAS DP equipment can be displayed on a designated function interface; further, a user (e.g., administrator) may select an interface from the interfaces exposed by the UCM device and designate the interface to initiate BRAS services.
For example, the user may select an interface on a functional interface where the UCM device presents the interface of the target BRAS DP device, and select a BRAS service initiation option in a function menu to trigger the interface of the target BRAS DP device to initiate BRAS service.
When the UCM device detects an operation instruction for starting the BRAS service of an interface of the target BRAS DP device, it determines that the BRAS service starting instruction for the interface of the target BRAS DP device is received, and further, the UCM device may allocate the target BRAS CP device to the interface of the BRAS DP device.
In one embodiment of the present invention, the allocating a target BRAS CP device from BRAS CP devices to a target BRAS DP device in BRAS DP devices, may include:
and selecting the BRAS CP equipment with the lowest resource utilization rate from the BRAS CP equipment as the target BRAS CP equipment.
In this embodiment, when the UCM device receives a BRAS service start instruction for a target BRAS DP device, the UCM device may traverse BRAS CP devices in a BRAS CP resource pool, and select a BRAS CP device with the lowest resource usage rate as the target BRAS CP device, so as to implement load balancing of each BRAS CP device in the BRAS CP resource pool.
It should be noted that, in this embodiment, when there are multiple BRAS CP devices with the lowest resource utilization rates, one BRAS CP device with the lowest resource utilization rate may be randomly selected as the target BRAS CP device, or one BRAS CP device with the lowest resource utilization rate may be selected as the target BRAS CP device according to another policy, for example, the BRAS CP device with the earliest creation time (or the latest) and the lowest resource utilization rate is selected as the target BRAS CP device, and specific implementation thereof is not described herein again.
In another embodiment of the present invention, the allocating a target BRAS CP device from BRAS CP devices to a target BRAS DP device in BRAS DP devices may include:
and selecting the BRAS CP equipment from the BRAS CP equipment as the target BRAS equipment in a polling mode.
In this embodiment, when the UCM device receives a BRAS service start instruction for a target BRAS DP device, the UCM device may select a BRAS CP device from a BRAS CP resource pool as the target BRAS device in a polling manner, so as to implement load balancing of each BRAS CP device in the BRAS CP resource pool.
It should be appreciated that the manner of selecting the target BRAS CP device described in the foregoing embodiments is merely two specific examples of selecting the target BRAS CP device in the embodiments of the present invention, and does not limit the scope of the present invention.
In the embodiment of the invention, after the UCM determines the target BRAS CP equipment for processing the control message of the target BRAS DP equipment, the UCM can send the configuration instruction to the target BRAS DP equipment through the Netconf connection between the UCM and the target BRAS DP equipment, and send the configuration instruction to the target BRAS CP equipment through the Netconf connection between the UCM and the target BRAS CP equipment.
The configuration instruction is used for indicating the target BRAS DP equipment to establish connection with the target BRAS CP equipment, and the connection is used for message interaction between the target BRAS DP equipment and the BRAS CP equipment.
In one embodiment of the present invention, the issuing the configuration instruction to the target BRAS DP device and the target BRAS CP device through the Netconf connection respectively may include:
respectively issuing a first type configuration instruction to target BRAS DP equipment and target BRAS CP equipment through Netconf connection so as to enable the target BRAS DP equipment and the target BRAS CP equipment to establish first connection; the first connection is used for interacting a user online control message between target BRAS DP equipment and target BRAS CP equipment;
respectively issuing a second type configuration instruction to target BRAS DP equipment and target BRAS CP equipment through Netconf connection so as to enable the target BRAS DP equipment and the target BRAS CP equipment to establish second connection; and the second connection is used for interacting the user flow control message between the target BRAS DP equipment and the target BRAS CP equipment.
In this embodiment, after the UCM device determines the target BRAS CP device for processing the control packet of the target BRAS DP device, on one hand, the first type configuration instruction may be sent to the target BRAS DP device through the Netconf connection with the target BRAS DP device, and the first type configuration instruction may be sent to the target BRAS CP device through the Netconf connection with the target BRAS CP device.
The first type configuration instruction is used for instructing a target BRAS DP device to establish a first connection with a target BRAS CP device, where the first connection is used for interacting a user online control message between the target BRAS DP device and the BRAS CP device, and the user online control message may include a Point to Point Protocol over Ethernet (PPPOE-based Point-to-Point Protocol over Ethernet) user or an IPOE (Internet Protocol over Ethernet-based Internet Protocol) user.
The first type configuration command sent to the target BRAS DP device (or target BRAS CP device) carries relevant information required when the target BRAS DP device (or target BRAS CP device) establishes the first connection.
Optionally, the first connection may be a VXLAN (Virtual Extensible Local Area Network) tunnel; correspondingly, the first type configuration instruction sent to the target BRAS DP device (or the target BRAS CP device) carries relevant information required when the target BRAS DP device (or the target BRAS CP device) establishes the VXLAN tunnel (for specific information, reference may be made to relevant implementation of existing VXLAN tunnel establishment, which is not described herein again in the embodiments of the present invention).
After the target BRAS DP equipment and the target BRAS CP equipment establish a VXLAN tunnel, user online control messages can be interacted through the VXLAN tunnel.
On the other hand, the UCM device can also send the second type configuration instruction to the target BRAS DP device through the Netconf connection with the target BRAS DP device, and send the second type configuration instruction to the target BRAS CP device through the Netconf connection with the target BRAS CP device.
The second type configuration instruction is used for indicating the target BRAS DP device to establish a second connection with the target BRAS CP device, the second connection is used for interacting a user flow control message between the target BRAS DP device and the target BRAS CP device, and the user flow control message comprises a control message interacted after a PPPOE user or an IPOE user is online, such as user flow table issuing, user flow reporting and the like.
The second type configuration command sent to the target BRAS DP device (or target BRAS CP device) carries relevant information required when the target BRAS DP device (or target BRAS CP device) establishes the second connection.
Optionally, the second connection may be an openflow connection; correspondingly, the second type configuration instruction sent to the target BRAS DP device (or the target BRAS CP device) carries relevant information required when the target BRAS DP device (or the target BRAS CP device) establishes openflow connection (for specific information, reference may be made to relevant implementation of establishment of openflow connection, which is not described in detail in the embodiments of the present invention).
After the openflow connection is established between the target BRAS DP equipment and the target BRAS CP equipment, user flow table issuing and user flow reporting can be carried out through the openflow connection.
It should be noted that, in the embodiment of the present invention, when the UCM device performs BRAS CP allocation with the interface of the BRAS DP device as granularity, after the target BRAS DP device and the target BRAS CP device establish a first connection and a second connection for an interface, the corresponding relation between the interface and the first connection and the second connection needs to be recorded, for example, the UCM device may record the correspondence between the interface and the first connection and the correspondence between the interface and the second connection respectively, or, the UCM device may record the correspondence between the interface and the first connection and the second connection, and the first connection and the second connection corresponding to the interface are inquired according to the corresponding relation, so that the interaction of a control message aiming at the interface, the issuing of a user flow table, the reporting of user flow and the like can be realized through the first connection and the second connection and the target BRAS CP equipment.
Optionally, in this embodiment of the present invention, the first connection and the second connection may use the same source IP address and destination IP address, and in this case, after the first connection and the second connection are established, only the corresponding relationship between the interface and the first connection (or the second connection) may be recorded.
For example, assuming that the first connection and the second connection are a VXLAN tunnel and an openflow connection, respectively, when the VXLAN tunnel and the openflow connection are established between the target BRAS DP device and the target BRAS CP device in the above manner, the same source IP address and destination IP address may be used, after the VXLAN tunnel and the openflow connection are established, the target BRAS DP device may record a correspondence between an interface and a VXLAN ID, and further, the target BRAS DP device may query the VXLAN tunnel and the openflow connection corresponding to the interface according to a correspondence between the interface and the VXLAN ID recorded by the target BRAS DP device; wherein, the VXLAN ID is assigned and notified to the target BRAS DP device and the target BRAS CP device by the UCM device after assigning the target BRAS CP device to the interface of the target BRAS DP device, for example, the VXLAN ID is notified to the target BRAS DP device and the target BRAS CP device by the first type configuration instruction; after the target BRAS DP device and the target BRAS CP device establish the VXLAN tunnel, the VXLAN ID needs to be associated with the established VXLAN tunnel.
It can be seen that, in the method flow shown in fig. 2, by adding the UCM device in the BRAS transfer separation architecture, the UCM device can allocate a target BRAS CP device from the BRAS CP device to a target BRAS DP device in the BRAS DP device, and control the target BRAS CP device to establish a connection for performing control packet interaction with the target BRAS DP device, and then control packet interaction between the target BRAS CP device and the target BRAS DP device is directly performed without being shunted by a centralized load balancing device, so that a performance bottleneck and a single point fault risk are avoided, a resource pooling scale is increased, and an online rate of a user is increased.
In order to enable those skilled in the art to better understand the technical solution provided by the embodiment of the present invention, the technical solution provided by the embodiment of the present invention is described below with reference to a specific application scenario.

Based on the application scenario shown in fig. 3, the implementation flow of the packet forwarding method provided in the embodiment of the present invention is as follows:
1. the UCM device initially creates a BRAS CP device, establishes Netconf connection with the BRAS CP device, and then automatically creates a new BRAS CP device according to the load of the existing BRAS CP device to form a BRAS CP resource pool;
for example, the UCM device may create a new BRAS CP device when the resource usage of an existing BRAS CP device exceeds a preset threshold (e.g., 70%, 80%, etc.).
2. When BRAS DP equipment is initialized to run, establishing Netconf connection with UCM;
the BRAS DP equipment only needs to enable Netconf in default configuration, and configures an opposite terminal as UCM equipment, and further, when the BRAS DP equipment is initialized to run, the BRAS DP equipment can establish Netconf connection with the UCM according to the default configuration.
Therefore, in the embodiment of the invention, the BRAS DP device only needs to configure the UCM device information when leaving the factory, and compared with the realization that the BRAS DP device in the existing BRAS transfer and control separation architecture needs to respectively configure different BRAS CP device information according to different BRAS CP devices allocated by the BRAS DP device, the factory configuration of the BRAS DP device is simplified.
3. After the BRAS DP equipment and the UCM equipment establish Netconf connection, reporting interface information to the UCM equipment, and displaying all interfaces of the BRAS DP equipment on a designated function interface by the UCM equipment;
after the UCM device displays all the interfaces of the BRAS DP device on the designated functional interface, a user (such as an administrator) may view all the interfaces of the BRAS DP device and select an interface to start the BRAS service.
In the embodiment, the user selects the interface g1/0/1 of the BRAS DPn to start the BRAS service as an example; wherein n is a natural number.
4. When UCM equipment receives a BRAS service starting command aiming at an interface g1/0/1 of BRAS DPn, BRAS CP equipment for processing a control message received by the BRAS DPn from the interface g1/0/1 is selected from a BRAS CP resource pool;
in this embodiment, the UCM device selects the BRAS CP device (assumed as BRAS CPm) with the lowest resource utilization rate in the BRAS CP resource pool to process the control message received by the BRAS DPn from the interface g 1/0/1.
5. The UCM equipment respectively issues VXLAN tunnel configuration instructions to BRAS DPn and BRAS CPm through Netconf connection, and a VXLAN tunnel is established between the BRAS DPn and the BRAS CPm;
in this embodiment, the VXLAN tunnel configuration instruction needs to carry a VXLAN ID assigned by the UCM device, and after a VXLAN tunnel is created between the BRAS DPn and the BRAS CPm, the VXLAN ID needs to be associated with the established VXLAN tunnel;
in addition, the UCM device also needs to inform the BRAS DPn of the interface for starting the BRAS service as interface g1/0/1, and after the UCM has created the VXLAN tunnel, the UCM needs to record the corresponding relationship between the VXLAN ID and interface g 1/0/1;
6. the UCM equipment issues openflow connection configuration instructions to the BRAS DPn and the BRAS CPm through Netconf connection respectively, and openflow connection is established between the BRAS DPn and the BRAS CPm;
wherein the openflow connection has the same source IP address and destination IP address as the VXLAN tunnel;
7. and the BRAS DPn and the BRAS CPm carry out user online control message interaction, user flow table issuing and user flow reporting aiming at the interface g1/0/1 through the VXLAN tunnel and openflow connection.
The BRAS service configuration of other interfaces on BRAS DPn or interfaces of other BRAS DP devices can be obtained in the same manner, and the embodiment of the present invention is not described herein again.
As can be seen from the above description, in the technical solution provided in the embodiment of the present invention, by adding the UCM device in the BRAS transfer separation architecture, the UCM device can allocate a target BRAS CP device from the BRAS CP device to a target BRAS DP device in the BRAS DP device, and control the target BRAS CP device to establish a connection for performing control packet interaction with the target BRAS DP device, and then the control packet interaction between the target BRAS CP device and the target BRAS DP device is directly performed without being shunted by a centralized load balancing device, thereby avoiding the existence of a performance bottleneck and a single point failure risk, improving the resource pooling scale, and simultaneously improving the online rate of a user.
